939574 ÷ 3 
We want to divide 939574 by 3.

On to step 1:
3 goes into 9 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

On to step 2:
3 goes into 3 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Going ahead to step 3:
When dividing 9 by 3, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 313.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Moving on to step 4:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 3131.0
If we take 3 away from 5, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

On to step 5:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 31319.0
Deduct 27 from 27 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

On to step 6:
4 divided by 3 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 313191.0
If we take 3 away from 4, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 313191.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 313191.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 313191.33 with a remainder of 0.001.
